A recent article in many papers in Australia, highlight a rise in illegal homeschooling practices.
Though even those Christian homeschooling groups claiming legality are suspicious as I've found references to extremely delusional drivel in books by nutjob authors such as John D. Martin "Living Together On God's Earth", and even links to Christian book shops in Texas, and their A.C.E. texts.
One commercial Christian homeschooling network made this statement on their home page.
This group calls themselves: HomeSchool Christian Academy
This group provides links to providers which stock creationist material.
This was not started by qualified educators but a delusional family (hacks) who simply performed their own homeschooling and now make a business from it.
These groups are those publishing their homeschooling and consider themselves legitimate.
Yet, if they are giving an education where god is involved with science, imagine the stupidity that the illegal homeschooling community would likely be indoctrinating their children with.
Chances are that any of their homeschooled children wanting a career in the sciences, wouldn't have a hope, since there does not appear to be any genuine critical thinking taught in their system.
And critical thinking skills are extremely necessary for a career in science.
By denying children critical thinking skills in this age of information, is tantamount to committing child abuse.
